Admin Raw ID widgets can show broken magnifying glass link

[Ramiro Morales]

This can happen when the related model isn't registered with the same admin site.

Ideally these widgets should behave in a way consistent with the regular non-raw ID admin widgets in this regard.

Example:

# models.py

from django.db import models

class Honeycomb(models.Model):
    location = models.CharField(max_length=20)

class Bee(models.Model):
    honeycomb = models.ForeignKey(Honeycomb)

# admin.py

from django.contrib import admin

import models

class BeeAdmin(admin.ModelAdmin):                                                                                                                                            
    raw_id_fields = ('honeycomb',) 

admin.site.register(models.Bee)

Try to add a Bee instance, in the add view click in the magnifying glass besides the 'Honeycomb' field, this leads to a 404 error.

I see no reason for

except NoReverseMatch: 
    raise 

Aside from that it looks good I guess ;)

Fixed #16542 -- Made Raw ID form widgets shipped with the admin app render the related object lookup tool only when the related model is effectively registered with the AdminSite.

Also, converted these widgets to reverse named URLs instead of hard-coded '../../...'-style links, refs #15294.
Thanks Florian Apolloner for the initial patch.
